Description

How Did Life Begin? There are two scientific views on the origins of life: 1) Earthly-Abiogenesis which argues life on Earth began on Earth, and 2) Extraterrestrial Abiogenesis the position of which is life has an ancestry which predates the origins of Earth, and is pervasive throughout the cosmos. Thus, both theories embrace abiogenesis" and both argue that life may have begun on innumerable planets via the same mechanisms. In this ground-breaking, revolutionary text, over 30 top scientists from around the world, explain how life began and if there is life on other worlds, in over 20 paradigm busting chapters.
